ADJUSTING DEVICE FOR WHEEL-PLOWS.

SPECIFICATION formi ngpart of Letters Patent No. 400,977, dated April 9,1889.

Application filed December 6, 1888. Serial No. 292,801. (No model.)

To all whom it may concern.-

Be it known that I, AUGUST JACOB VENTZKI, a subject of the King ofPrussia, German Emperor, and a resident of the city of Graudenz, in theKingdom of Prussia, Germany, have invented certain new and usefulImprovements in Adjusting Devices for Wheel-Flows; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

The object of the present invention is to' construct a wheel-plowwhereby the furrowwheel'and the land-wheel may be moved by means of asingle hand-lever in such a way that the furrow-wheel will always be ata level with the bottom of the plow, while the land-wheel, for thepurpose of regulating the depth of the furrow, can be either raised orlowered independently of the furrow-wheel,

which remains in its original working position.

In the accompanying drawings, Figure 1 represents a side view of theplow in working position. Fig. 2 shows the same plow in po sition fortransportation. Fig. 3 represents a roller to be used for thetransportation of the plow. Fig. 4 is a top view of the plow.

The axle ais secured in such a manner on the frame A that it can befreely turned. The crank 19 for the furrow-wheel F is fastened by meansof the staple is, so that this crank may be moved both in a horizontaland a vertical direction. The object of the horizontal adjustment of thefurrow-wheel F is to provide for placing this wheel always in the lastfurrowas, for instance, if it should be necessary to transform a plowwith three shares into one with two shares, as shown by the dottedposition in Fig. 4. The adjustment of the crank 12 in a verticaldirection makes it possible to bring the furrow-wheel to a level withthe bottom of the plow when the shares shall have been worn off.

Another and very important object of the vertical adjustability of thefurrow-wheel is to make it feasible to raise the crank b with thefurrow-wheel F when commencing to plow, so as to give at once thedesired depth to the first furrow. At the other end of the axle a, Fig.4, the slotted curved lever S is attached. A stud, p, projecting fromthe elbow-lever W,

(the other end of which carriesthe axle b of the land-wheel L,) worksfreely in the slot of the lever S. The movement of the elbow-lever W,and consequently the throwing into working position of the tWo wheels Fand L, is effected by the hand-lever H, connected with the elbow-leverW, and the catch 0 of the lever catching in the teeth of the segment Bafter slipping over the smooth partof it. During the movement of thehand-lever H from its lowest position necessary for the transportationof the plow, Fig. 2, until its catch reaches the toothed portion of thesegment B, the stud p will turn the lever S from the position shown inFig. 2 to the position represented in Fig. 1. This causes thefurrow-wheel F, which until then was in line with the land-wheel L, tobe swung forward, and said furrow-wheel, if the crank b is correctlyadjusted, will then be on a level with the bottom of the plow, Fig. 1.

This done, the land-wheel L is adjusted according to the desired depthof furrow, which is effected by moving the hand-lever. H farther forwardon the teeth of the segment B.

In the meantime the position of the furrowwheel will remain unchanged,because the stud 'p is moved from the straight portion of the slottedlever S into the curved portion at the same moment that the catch of thehandlever catches in the first tooth of the segment B, (position shownin Fig. 1,) and said curve being concenti ie to the segment B it isevident that with a continued movement the stud 19 must leave theslotted lever S unaifected. This lever and consequentlythe furrow-wheelremain unchanged in theposition given them by turning the hand-lever Hto the point where the teeth commence, this position being with respectto the furrow-wheel on a level with the bottom of the plow. During thismovement, however, the land-wheel has not remained in its originalposition, but has been moved backward from the position shown in Fig. 2to the one shown in Fig.1. By further moving the hand-lever llforinstance, to the position shown by the dotted lines in Fig. 1theland-wheel L is raised and will occupy the position represented by thedotted lines. This peculiar arrangement makes it possible that thefurrowwheel is always placed on a level with the bottom of the plow whenworking without causing the same to run awry. As a consequence of thebackward movement of the land-wheel, this plow possesses the advantagepresented by the wellknown plow with three wheelsna1nely, thedisburdening of the body of the plow by the landwheel without possessingthe disadvantage of those plows-which consists in the fact that duringthe work one wheel runs over the loose field or is suspended in the air,and consequently causes a one-sided burdening of the plow.

For the purpose of transportation, the roller T, Fig. 3, is attached tothe slide Gr- The lowering and raising apparatus for wheel-plowsdescribed above may of course be changed in its non-essential partssuchas the parts connecting the lowering and raising mechanism with theland-wheel without materially affecting the invention. Such analteration is shown in Figs. 1, 1", 2, and 4: of the drawings. Figs. 1and 1 show a side view of the plow in working position. Fig. 2 shows theplow with two shares in the position for transportation with annexedroller. Fig. 4 represents a top view with the eolter in position.

The parts already described in their construction and operation are alsoapplied in those figures, and are designated by the same letters as inFigs. 1 to 4.. For the elbowdever V the following arrangement has,however, been substituted: The hand-lever H is double-armed, carrying onits short arm a stud, 1), and resting with this stud in the slottedlever S, and carrying, besides, the segment q, the

center of which is at the same time the fulcrum for the hand-lever H. Atthe same time this fulcrum is the pivot of the crank-shaft r of theland-wheel L, and this shaft 7' is connected with the segment (1 by aside block, g. The only object of the segment q is to create a morefavorable transmission of the working-point of the lifting-power to theaxle of the land-wheel than that represented in Fig. 1, and thereby todecrease the cost of manufacture of the plows.

The raising of the lever H from its first catch involves a raisingmovement of the land-wheel L more or less, according to the selectedcatch, the furrow-wheel F remaining meanwhile in its place. If, on thecontrary, the hand-lever H is lowered, Fig. 2, the landwhecl is alsolowered, approaching therewith the furrow-wheel. The latter is in themeantime also lowered (the stud p of the handlever reaching the straightpart of the forked lever S) and moved backward, so that the position fortransportation will be obtained.

If it is desired to use a eolter, V, the same might be adjusted to theframe, as shown in Fig. 4.

What I claim as new, and desire to secure by Letters Patent, is

In a wheel-plow, a lowering and raising apparatus for furrowwheel andland-wheel, characterized by the arrangement of a slotted lever, S,curved at one end concentric to the segment B of the hand lever H, butstraight or curved not concentric to the segment 13 atthe other end, thefixed axle a of said slotted lever being also the pivot for thefurrow-wheel F, while the pivot of land-wheel. L is at the same time thefulcrum of the handlever 11, substantially as herein shown anddescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

AUGUST JACOB VENTZKI.
